LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 267,074, dated November 7, 1882.

' Application filed September 27, 1882. (No model.)

To all whom it may concern:

Be it known that I, WALTER M. GERMOND, a citizen of the United States, residing in Baltimore,'lVIaryland, have invented a new and useful Improvement in Lubrioators, of which the following is a specification.

My invention relates to lubricators, and will be first fully described, and then particularly pointed. out in the claims.

Referring to the accompanying drawing, which is a sectional view of my devicein working position, A is a tube having a screw-thread out on its exterior central portion. B is a milled hand-nut, interiorly threaded to engage the exterior threads on tube A. O is a washer. D is a cylinder of gum or cork. H is a rib or shoulder surrounding and forming part of tube A. E is a screw-valve working in the tube A.

F is a bottle or other vessel, usually made of glass. fis the neck of bottle F. G is an openingin one sideof tube A. a is the cap ofa bearing, c, of a shaft, 12, which cap has an opening or oil-hole, d.

The tube A is usually made of brass or other metal, and is furnished, as before stated, with a shoulder, H. The cork or gum cylinder D is placed on the tube, resting on said rib H. The washer O is now put on, after which the nut B is screwed down to the washer. The

valve E is now adjusted so as to leave open any desired'portion of the opening G. The tube thus adjusted is inserted into the neckf until the cork or gum reaches the neck. The nut B is now turned forcibly down against the washer, forcing it against the cork 0r gum, which, being prevented by the shoulder H from moving longitudinally of the tube, is necessarily expanded laterally, thus tightly closing the neck f. The bottle and tube, being thus rigidly connected together, are now inverted (the bottle being filled with oil) and the point of the tube inserted in the opening (1 in the bearing of the shaft b, where itis allowed to remain until all the oil has been drained ofi, when it can be removed and refilled.

If by accident the bottle should be broken it can be replaced by another at a very small expense, no fitting or other expensive work being necessary.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. The combination of the tube A, having rib H and exterior thread, with the cork or gum cylinder H and not B, as set forth.

2. The bottle F, having neekf, in combination with tube A, having shoulder H and exterior thread, the cork or gum cylinder, and the not B, as set forth.

3. In an automatic lubricator, an oil-reservoir, a cylindrical flexible packing, means for laterally expanding the same, a feed-tube, and means for regulating the eil-supply, all constructed and combined substantially as set forth.

In testimony whereof I have hereto subscribed my name.
